Which equation hasd a graph parallel to the graph of 9x+3y=-22
tatyana61 [14]

Answer:

<h2>3x + y = b</h2>

<em>b - </em><em>any real number</em>

Step-by-step explanation:

Parallel lines have the same slope.

We have the equation of a line in the standard form <em>Ax + By = C</em>.

Convert to the slope-intercept form <em>y = mx + b</em>

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

9x+3y=-22         <em>subtract 9x from both sides</em>

3y=-9x-22         <em>divide both sides by 3</em>

y=-3x-\dfrac{22}{3}

Therefore we have the slope <em>m = -3</em>.

Put it to the equation of a line:

y=-3x+b            <em>add 3 to both sides</em>

3x+y=b

What is 4 . 9 equal 9 . 4
Nostrana [21]

4/9 is the lowest number, you can't simplify it, but, you can go up, so 8/18 is also equal to 4/9 I think.

Which has more moles 2SO3(g) or 2SO2(g) + O2(g)
shusha [124]

Answer:

2SO2(g) + O2(g)

Step-by-step explanation:

2SO2(g) + 02(g) = 2SO4(g)

and...

2SO3(g) < 2SO4

so that makes  2SO2(g) + O2(g) a bigger number

Write a number that has four digits with same number in all places, such as 4,444. circle the digit with the greatest value. und
siniylev [52]

Easy.

Your number would be 2,222 and you'd circle the first 2 (starting from the left) and underline the last 2(again, starting from the left).

The reason why you'd underline the last 2, is because the very last number would represent the ones place. The first 2 would be the thousands place. Meaning that 2,222 would translate to two-thousand two-hundred twenty-two.
